Final answer:
Positive reinforcement involves adding a desirable stimulus, while negative reinforcement involves removing an undesirable stimulus to increase a behavior.
Step-by-step explanation:
Positive reinforcement and negative reinforcement are two different concepts in operant conditioning. Positive reinforcement involves adding a desirable stimulus to increase a behavior, while negative reinforcement involves removing an undesirable stimulus to increase a behavior. For example, if you receive a reward for completing a task, that is positive reinforcement. If an annoying sound stops when you buckle your seatbelt, that is negative reinforcement.
